* Run the core CPU loop

* hardware. This is much faster than SingleStep (and should be equivalent), as the CPU is not
* required to do a full dispatch with each instruction. NOTE: the number of instructions requested
* is not guaranteed to run, as this will be interrupted preemptively if a hardware update is
* requested (e.g. on a thread switch).
